DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 482,370, datedSeptember 13, 1892.

Application filed May 22, 1890. $eri al No. 352,808- (No model.)

To all whom it may concern:

Be itknown that I, JOHN LAMUTH, a citizen of the United States, residingat Irvington, Ko'ssuth county, State of Iowa, have invented a new anduseful Four-Horse Equalizer or Evener, of which the following is aspecification.

My invention relates to an equalizer to be used on harvesters, plows, orother machines or vehicles where it is desirable to use or drive fourhorses abreast; andthe objects of the invention are, first, to use fourhorses abreast; second, to equalize the draft of said horses, so thateach one will draw his proper and proportionate amount of load or do hisproper or proportionate amount of the work. I attain these objects bythe mechanism shown in the accompanying drawings,in which- Figure 1 is aplan View of my improved four-horse equalizer. Fig. 2 is a detail View,partly in section, showing the main levers and their connection with thetongue; and Fig. 3 is another detail view showing the manner ofconnecting a blockrto the tongue near the end of the latter.

Fig. 1 exhibits afour-horse evener or equalizer, by which four horsesmay be driven or worked abreast on any harvester, plow, or in any workwhere four horses are necessary or desirable.

a (1 denote two levers, which are connected to the tongue and togetherconstitute the main cross-bar, which two pieces are joined by a pin atthe point marked with the figure 2, arranged with a joint, so as to beworked separately.

0 is a shorter cross-bar fastened on top of the main cross-bar a with aclevis-pin to the right of the center, being in effect a threehorseevener.

o is a short bar attached by two straps of iron (one over and one under)to the crossbar b, being in effect a two-horse evener.

d d d d are singletrees for four horses, as contemplated by the design.

e is a curved iron bar attached by a clevis and pin to the block h,being the equalizer,

andoperated by the iron rods f and g, extending from the same to thecross-bar a, as shown in Fig. l.

h is a block attached to tongue or pole of harvester or other machine onwhich the fourhorse evener or equalizer is used. There is a cross-braceit from near the outer end of the block h to the pole or tongue.

'0' is an iron brace under the block 71 for the purpose of strengtheningsaid block.

j is an iron brace under the long arm of the main cross-bar a andattached thereto and to the tongue or pole for the purpose ofstrengthening the same and holding said crossbar a up in position.

is is the iron cross-brace above referred to.

I claim- 1. In a draft-equalizer, the combination of the main tongue,the whiftletrees, the trans verse levers a a, joined together at theircontiguous or meeting ends and pivoted at that point upon the tongue,the rear curved bar 6, pivotally supported upon the horizontal block h,attached to the tongue and projecting outward therefrom on one sidethereof, it being firmly supported by means of a brace, a rod f,extending from one end of the curved bar e to the oppositely-locatedmain lever a, and the rod g, extending from the other end of the bar 6to the other of the levers a, said rods f and 9 being pivotally attachedat their ends, all arranged to operate substantially as described.

2. The combination of the tongue, the levers a a, joined together andpivoted to the tongue by means of the pivot 2, the whittletrees d, thebrace j, the cross-bar I), supported on one lever a, the cross-bar 0,supported on cross-bar b, the block h, attached to the tongue, curvedbar 6, pivoted to block h, and the rods f and g, connected at theirouter ends to the levers a a and at their inner ends to the ends of thecurved bar 6, substantially as described.

JOHN LAMUTH.
